Unsere Werkstoffe - GOLF+STEEL

Only the best materialsTested and certified

At GOLF+STEEL we use various metals such as steel, corten, stainless steel and aluminium to manufacture our products. We achieve our extremely high-quality looks through different surface finishes and coatings. You have the choice.

Stainless steel

The terms stainless steel, Nirosta and VA stand for a noble, non-rusting steel.

We offer these stainless steels with ground, brushed or blasted surfaces.

The reason for the high corrosion resistance lies in the chemical composition. With these steels, a thin protective layer forms on the surface, the passive layer. Under the influence of oxygen, this layer can renew itself and thus forms a natural surface protection.

Under certain conditions, however, normal V2A stainless steel can also rust when used outdoors. It can be problematic, for example, with salty or chlorinated air. The higher quality material V4A should be used in swimming pools or at the sea. This material is particularly resistant to chlorine and acid. However, both materials are not protected against the adhesion of foreign particles. Here there is a risk of rusting due to e.g. iron particles in the air or road salt. Stainless steels should therefore also be cleaned regularly. If the contamination has not been on the object for a long time, you can simply wipe off the flash rust with a soft cloth. Otherwise we offer a stainless steel cleaner for the removal of the contamination. Together in use with our stainless steel care oil your objects are optimally protected in the outside area.

Corten steel - sheets with stainless steel

As early as the 19th century, corten steel was used, for example, for the construction of bridges. A steel alloy had been developed with additions of copper, nickel, phosphorus, silicon and chromium. A weather-resistant steel had been created. Today, due to its resistance to weathering and its characteristic patina, corten steel is often used for architectural accents, such as facade cladding or as elements of garden decoration.

Corten steel forms a particularly dense barrier layer of adherent sulphates or phosphates on the surface through weathering, underneath the actual rust layer, which protects the steel part from further corrosion. The formation of the surface begins with outdoor weathering after approx. two to three weeks and is completed after two to three years. It is important here to alternate between moisture and dryness. If parts of the object are not exposed to the weather, no patina will form and different shades may appear on the object.

It is good to know that corten steel has an extremely long life and is fully recyclable. This means that it is classified as an ecological material.

Objects made of corten steel are usually delivered to customers unrusted. This means that the steel looks rather greyish and metallic on delivery. There is no sign of rust yet. In this state of delivery the material is not really beautiful. But of course it should not remain like this.

If the material is exposed to the elements, the first signs of rust will appear after just a few days. Humidity is the decisive factor here. The higher the humidity or the more weather changes between dry and damp, the faster the rusting process takes place. After two to three weeks, the rusting is already more advanced and clearly visible.

When used indoors, pre-rusting is of course necessary.

Steel with powder coating

We offer many of our products with a coloured surface coating - powder coating. Powder coating is a coating process in which an electrically conductive material is coated with powder paint. A typical coating line consists of surface pre-treatment (cleaning and/or application of a conversion coating), intermediate drying, electrostatic coating zone and dryer. The workpieces are transported through a conveyor system.

For the products of our program we have fixed color shades RAL card in the program. However, for individualization and larger quantities, we are also able to offer other colors according to RAL or DB.

For outdoor objects, we use galvanized steel or stainless steel as the basic material. This ensures that the objects do not corrode.

For interior objects, raw steel is sufficient as a base or backing material.
